The Division of Sinus and Allergy works to provide the best sinus and allergy care available in Columbus and central Ohio as well as in the nation. Our department has been recognized as one of the top ear, nose and throat programs in America by US News and World Report Best Hospitals. Our top doctors and surgeons have been acknowledged nationally for their expertise in the diagnosis and treatment of sinus and allergy related disorders. The Division receives funding from the National Institutes of Health and other prestigious organizations to carry out research to help treat patients with severe forms of sinus disease and allergic disorders. The Division physicians specialize in the medical and surgical management of a broad range of diseases from nasal obstruction and rhinosinusitis to complicated conditions involving the nose, sinuses, and anterior skull base. We evaluate whether allergies are contributing to these problems and, if needed, provide allergy immunotherapy in the form of shots or drops. We work to improve each patient’s nasal and sinus health.
